angle TS = 74°
Straight line is 180°, so add PT and SR
(64+42 = 106)
Subtract 180 from 106, you get 74 :)

- Vertical Line Test - Shows if a graph is a function
Step-by-step explanation:
We see from the graph that we have a vertical line. Any vertical line will have an undefined slope.
Answer:
As the P-value is very low, we can conclude that there is enough evidence to support the claim that the survival rate is significantly higher when the seatbelt is used.
Step-by-step explanation:
We have a hypothesis test that compares the survival rate using the seatbelt versus the survival rate not using it.
The claim is that the survival rate (proportion) is significantly higher when the seatbelt is used.
Then, the null hypothesis is that the seatbelts have no effect (both survival rates are not significantly different).
The P-value is the probabilty of the sample we have, given that the null hypothesis is true. In this case, this value is 0.0001.
This is very low, what gives enough evidence to claim that the survival rate is significantly higher when the seatbelt is used.
